This was tested in people. That is the most reliable kind of research we share.
This was a look back at past patient records, not a treatment being tested.
The short version
Many people with a tumor in the parietal part of the brain had thinking trouble before surgery.
What was studied. Doctors looked back at records from two centers over 20 years. Forty-six adults with a parietal lobe tumor took thinking and memory tests soon after diagnosis, before surgery.
What they found. Grade 2 oligodendroglioma was the most common tumor type (45.6%). Among people with right-side tumors, 60% had trouble with abstract thinking and 43.5% had trouble learning and remembering. Among people with left-side tumors, 63.6% had trouble switching between tasks and 52.2% had trouble holding facts in mind.
What this means, and what it doesn't
What it could mean: Thinking problems can already be there before surgery. So a thinking and memory test early on may be worth asking about. It gives your team a starting point and shows where you may need help.
What it doesn't mean: This does not mean a new treatment. It was a look back at old patient records, not a test of any care plan. The left side and right side differences were not strong enough to be sure about. Nothing here says what will happen to you, and it is not a cure.
